|Abstract: ||The aim of this work was to achieve the surface finish of 10nm on a 40mm
diameter disc of chrome-molybdenum-vanadium alloyed steel (H13) by using
precision grinding process with electrolytic in-process dressing. The machine
tool utilized was Tetraform-C, its unique tetrahedral frame offered higher
structural stability. A cup grinding wheel with iron bonded CBN abrasive grit of
76 microns average size with 50% concentration was used. The statistical methods
were employed to determine the optimal combination of input parameters to
achieve the required response. The main effect of feed rate was found to be more
significant than the depth of cut and lower levels of these factors produced
better surface finish. The developed regression model based on the relationships
between process variables was used to predict factor levels to achieve the
required process response.|
